How is ADC designed?

Introduction. The ADC module of this MCU is based on a 12-bit Analog-to-Digital Converter (ADC) managed by an ADC Controller providing enhanced resolution up to 14 bits. It also integrates a 12-to-1 analog multiplexer, making possible the analog-to-digital conversions of 12 analog lines.

How does a analog to digital converter work?

ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the ADC are its sampling rate and resolution.

What converts analog to digital?

A modem is a device used to convert analog signals to digital signals and vice-versa.

What is DAC architecture?

The first architecture to consider is the string DAC or sometimes called the Kelvin divider DAC. The string DAC is one of the simplest methods to realize a DAC and is simply a collection of resistors in series with switching points or tap nodes between each of the resistors.

Which component is in the ADC?

These ADCs are perhaps the most accurate. They consist of a comparator, a simple flash DAC and a memory register. The device initially assumes all the bits in the register except for the highest significant bit (which is a one) to be zeroes.

How is ADC digital output calculated?

ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.

What is DAC circuit?

Digital to Analog Converter (DAC) is an integrated circuit that converts digital signal to analog voltage/current which is necessary for further Analog Signal Processing.
